The current issue?
https://bugzilla.openvz.org/show_bug.cgi?id=3161

Fixed? Seems yes, here:
https://openvz.org/Download/kernel/rhel6/042stab094.7/changes

fs/aio: aio_nr & aio_max_nr variables virtualization (PSBM-27188)
fs/aio: introduce aio_nr & aio_max_nr per-CT sysctls (PSBM-27188)

But, how to do? I don't find any documentation :(
Any idea?

Thanks!
